COMPOSITION FOR NEUTRALIZING FUMES OF EXPLOS'lVES.

SPECIFICATION forming part of Letters Patent No. 354,345, dated Decemnci 1%, Gb.

App'ihtion filed Dcromhcr'l, 1%!!35. Serial X0. IRLQDB. (No specimens.)

To all whom it may concern:

Be it known that I, Tnoams Pinon, a cilizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Means for Neutralizing the Fumes from the Explosion of IIiglrExplosive Compounds, of which the following is a specification.

It is a well-known fact that heretofore in the use of nitroglycerine and other explosive compounds a considerable lapse of time musttake place after the explosion before the miner can enter the mine with safety, owing mainly to the nauseating fumes evolved from such explosions; hence the object of my invention is to so neutralize these obnoxious fumes as to admit of an immediate entrance into the mine as soon as the explosion has taken place, and without nauseating or having any injurious uid state.

cfi'ect upon the person or persons so entering. With this end in view I employ a small tube composed of thin metal or other material capable of being easily affected by percussion or concussion. I fill this tube with carbonate of ammonia, urate of ammonia, solution of agent is hermeticallysealed and placed within the cartridge 13, composed of nitro-glycerine or other explosive compound,just beneath the percussion-cap G, by which the cartridge is exploded, so that at the time the detonation or explosion of the cartridge takes place the tube or capsule will be disrupted and the 0011- tents decomposed and a neutralizing vapor from the decomposed agent be evolved and saturate the fumes generated by the exploded cartridge, clearing up the atmosphere and neutralizing the gases, so that occupation of the compartment or mine may take place at once without nausea or injury to the person or persons so entering. By this means much time will be saved, as the workmen can enter upon their labor immediately after the explosion takes place.

Having thus described my invention, whatI claim, and desire to'seeure by Letters Patent, 1s-

The composition herein described for neutralizing the fumes generated by the explosion of nitro-glycerinc or otherhigh-explosive compounds, consisting of carbonate of ammonia, urate of ammonia, lime, and sulphate of iron, in the proportions described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
